能量均衡分簇算法在传感器网络中的应用

Energy Balanced Clustering Algorithm Applications in Sensor Networks

无线传感器网络存在能量约束问题,网络簇头能量消耗不均衡和簇头的瓶颈等问题都是因为LEACH算法中簇首分布不均会造成的。为了解决这些问题,提出了一种新的算法,也就是基于能量高效网络分簇路由算法。为了让簇头均匀地分布在网络中,通过节点的能量、邻节点数确定出簇头的优先度。通过能量参数设置簇组建,大大降低了簇的重建频率。

The wireless sensor network energy constraint problem, LEACH algorithm cluster head in the une- yen distribution caused by the uneven distribution of the network cluster head which will result in energy consump- tion is not balanced as well as the bottleneck of the cluster head. Based on energy-efficient wireless sensor network clustering routing algorithm to solve the above problem, the algorithm first in the cluster head selection process using the energy of the node, neighbor nodes and each round of cluster head node is elected the number of parameter set- tings of cluster head priority. So that the cluster head is uniformly distributed in the network. In the process of the formation of clusters using the energy parameter setting cluster reconstruction condition, the reconstruction of fre- quency of the cluster is reduced. Simulation results show that the improved algorithm can not only improve the net- work, the energy utilization rate, improve the stability of the network, but also can balance the network energy con- sumption, prolong the network life.
